Comment:

 Hey - had these errors (30+) in both Firefox and Chrome, using the
 Gutenberg widgets.php


 I have a feeling it's crashing other JS on the page and making inner-
 widget buttons unusable

 I actually have custom widgets in there that I initialised
 (functions.php), that are smoothly integrated and working with the classic
 widget area, but s'pose it is likely they're incompatible with the block
 editor



 **My solution** was installing the ''Classic Widgets'' plugin which fixed
 it instantly & without a single console error
